Kinda annoying that I cant do this boss on my green geared alts she just completely wrecks me before I can kill her

Does your alt lack healing spells? I mean, she does 12k hits when she broke the roof due to her stacking buff, easily healable considering you have ~350k hp+. Also, you could still try to kill a lot of adds in the middle of the room before they reach her. they only have like 6k hp. just sprint to the tainted elementals when they start throwing goo balls on you.

I had a lot of trouble doing it on my decently geared WW monk, but as MW or BrM it was easy. Hunter and warlock with tanking pets were trivial. DK and Paladin were trivial in tank specs (and my DK is geared anyway). Warrior can do it as DPS with second wind no problem, warriors never die. Didn't try my undergeared rogue, mage, shaman, or druid (but I bet I could do it np as bear). Rogue and mage would be rough, and shaman would be challenging too.

The strider doesn't continuously cast fear any more, but there's only a ~4s pause between fears. You need to get an instant-cast on him (SW:P). He has hilariously low health so a DoT tick or two will kill him. The SW:P DD component may be enough, actually.
